Position dependent recognition of GNN nucleotide triplets by zinc fingers

ABSTRACT

The specificity of binding of a zinc finger to a triplet or quadruplet nucleotide target subsite depends upon the location of the zinc finger in a multifinger protein and, hence, upon the location of its target subsite within a larger target sequence. The present disclosure provides zinc finger amino acid sequences for recognition of triplet target subsites having the nucleotide G in the 5′-most position of the subsite, that have been optimized with respect to the location of the subsite within the target site. Accordingly, the disclosure provides finger position-specific amino acid sequences for the recognition of GNN target subsites. This allows the construction of multi-finger zinc finger proteins with improved affinity and specificity for their target sequences, as well as enhanced biological activity.

BACKGROUND

Zinc finger proteins (ZFPs) are proteins that can bind to DNA in asequence-specific manner. Zinc fingers were first identified in thetranscription factor TFIIIA from the oocytes of the African clawed toad,Xenopus laevis. An exemplary motif characterizing one class of theseprotein (C₂H₂ class) is -Cys-(X)₂₋₄-Cys-(X)₁₂-His-(X)₃₋₅-His (where X isany amino acid) (SEQ. ID. No: 1). A single finger domain is about 30amino acids in length, and several structural studies have demonstratedthat it contains an alpha helix containing the two invariant histidineresidues and two invariant cysteine residues in a beta turn co-ordinatedthrough zinc. To date, over 10,000 zinc finger sequences have beenidentified in several thousand known or putative transcription factors.Zinc finger domains are involved not only in DNA-recognition, but alsoin RNA binding and in protein-protein binding. Current estimates arethat this class of molecules will constitute about 2% of all humangenes.

The x-ray crystal structure of Zif268, a three-finger domain from amurine transcription factor, has been solved in complex with a cognateDNA sequence and shows that each finger can be superimposed on the nextby a periodic rotation. The structure suggests that each fingerinteracts independently with DNA over 3 base-pair intervals, withside-chains at positions −1, 2, 3 and 6 on each recognition helix makingcontacts with their respective DNA triplet subsites. The amino terminusof Zif268 is situated at the 3′ end of the DNA strand with which itmakes most contacts. Some zinc fingers can bind to a fourth base in atarget segment. If the strand with which a zinc finger protein makesmost contacts is designated the target strand, some zinc finger proteinsbind to a three base triplet in the target strand and a fourth base onthe nontarget strand. The fourth base is complementary to the baseimmediately 3′ of the three base subsite.

The structure of the Zif268-DNA complex also suggested that the DNAsequence specificity of a zinc finger protein might be altered by makingamino acid substitutions at the four helix positions (−1, 2, 3 and 6) oneach of the zinc finger recognition helices. Phage display experimentsusing zinc finger combinatorial libraries to test this observation werepublished in a series of papers in 1994 (Rebar et al., Science 263,671-673 (1994); Jamieson et al., Biochemistry 33, 5689-5695 (1994); Chooet al, PNAS 91, 11163-11167 (1994)). Combinatorial libraries wereconstructed with randomized side-chains in either the first or middlefinger of Zif268 and then used to select for an altered Zif268 bindingsite in which the appropriate DNA sub-site was replaced by an alteredDNA triplet. Further, correlation between the nature of introducedmutations and the resulting alteration in binding specificity gave riseto a partial set of substitution rules for design of ZFPs with alteredbinding specificity.

Greisman & Pabo, Science 275, 657-661 (1997) discuss an elaboration ofthe phage display method in which each finger of a Zif268 wassuccessively randomized and selected for binding to a new tripletsequence. This paper reported selection of ZFPs for a nuclear hormoneresponse element, a p53 target site and a TATA box sequence.

A number of papers have reported attempts to produce ZFPs to modulateparticular target sites. For example, Choo et al., Nature 372, 645(1994), report an attempt to design a ZFP that would repress expressionof a bcr-abl oncogene. The target segment to which the ZFPs would bindwas a nine base sequence 5′GCA GAA GCC3′ chosen to overlap the junctioncreated by a specific oncogenic translocation fusing the genes encodingbcr and abl. The intention was that a ZFP specific to this target sitewould bind to the oncogene without binding to abl or bcr componentgenes. The authors used phage display to screen a mini-library ofvariant ZFPs for binding to this target segment. A variant ZFP thusisolated was then reported to repress expression of a stably transfectedbcr-able construct in a cell line.

Pomerantz et al., Science 267, 93-96 (1995) reported an attempt todesign a novel DNA binding protein by fusing two fingers from Zif268with a homeodomain from Oct-1. The hybrid protein was then fused with atranscriptional activator for expression as a chimeric protein. Thechimeric protein was reported to bind a target site representing ahybrid of the subsites of its two components. The authors thenconstructed a reporter vector containing a luciferase gene operablylinked to a promoter and a hybrid site for the chimeric DNA bindingprotein in proximity to the promoter. The authors reported that theirchimeric DNA binding protein could activate expression of the luciferasegene.

Liu et al., PNAS 94, 5525-5530 (1997) report forming a composite zincfinger protein by using a peptide spacer to link two component zincfinger proteins each having three fingers. The composite protein wasthen further linked to transcriptional activation domain. It wasreported that the resulting chimeric protein bound to a target siteformed from the target segments bound by the two component zinc fingerproteins. It was further reported that the chimeric zinc finger proteincould activate transcription of a reporter gene when its target site wasinserted into a reporter plasmid in proximity to a promoter operablylinked to the reporter.

Choo et al., WO 98/53058, WO98/53059, and WO 98/53060 (1998) discussselection of zinc finger proteins to bind to a target site within theHIV Tat gene. Choo et al. also discuss selection of a zinc fingerprotein to bind to a target site encompassing a site of a commonmutation in the oncogene ras. The target site within ras was thusconstrained by the position of the mutation.

Previously-disclosed methods for the design of sequence-specific zincfinger proteins have often been based on modularity of individual zincfingers; i.e., the ability of a zinc finger to recognize the same targetsubsite regardless of the location of the finger in a multi-fingerprotein. Although, in many instances, a zinc finger retains the samesequence specificity regardless of its location within a multi-fingerprotein; in certain cases, the sequence specificity of a zinc fingerdepends on its position. For example, it is possible for a finger torecognize a particular triplet sequence when it is present as finger 1of a three-finger protein, but to recognize a different triplet sequencewhen present as finger 2 of a three-finger protein.

Attempts to address situations in which a zinc finger behaves in anon-modular fashion (i.e., its sequence specificity depends upon itslocation in a multi-finger protein) have, to date, involved strategiesemploying randomization of key binding residues in multiple adjacentzinc fingers, followed by selection. See, for example, Isalan et al.(2001) Nature Biotechnol. 19:656-660. However, methods for rationaldesign of polypeptides containing non-modular zinc fingers have notheretofore been described.

(rightmost 3 columns). Analysis of ZFP1is shown in the upper portion of the figure and analysis of ZFP2 isshown in the lower portion of the figure. For the site selectionanalyses, the amino acid sequences of residues −1 through +6 of therecognition helix of each of the three component zinc fingers (F3 (ZFP1,SEQ ID NO:130; ZFP2, SEQ ID NO:420), F2 (ZFP1, SEQ ID NO:1051; ZFP2, SEQID NO:889) and F1 (ZFP1, SEQ ID NO:395; ZFP2, SEQ ID NO:685)) are shownacross the top row; the intended target sequence (divided intofinger-specific target subsites) is shown across the second row, and asummary of the sequences bound is shown in the third row. Data for F3 isshown in the second column, data for F2 is shown in the third column,and data for F1 is shown in the third column.

For the binding affinity analyses, the designed target sequence for eachZFP (“cognate”) and two related sequences (“Mt”) are shown (column 6),along with the K_(d) for binding of the ZFP to each of these sequences(column 7).

FIG. 2 shows amino acid sequences of zinc finger recognition regions(amino acids −1 through +6 of the recognition helix) that bind to eachof the 16 GNN triplet subsites. Three amino acid sequences are shown foreach trinucleotide subsite; these correspond to optimal amino acidsequences for recognition of the subsite from each of the threepositions (finger 1, F1 (SEQ ID NOS:688, 2534, 676, 1769, 342, 1450,131, 158, 1765, 395, 1407, 2644, 705, 1398, 1733 & 184); finger 2, F2(SEQ ID NOS:688, 229, 1446, 3051, 220, 1450, 417, 801, 1442, 395, 1824,1201, 972, 3339, 1151 & 184); or finger 3, F3 (SEQ ID NOS:943, 229, 676,1769, 220, 1365, 417, 801, 3525, 395, 1824, 1425, 972, 3592, 952 & 184))in a three-finger zinc finger protein. Amino acid sequences are fromN-terminal to C-terminal; nucleotide sequences are from 5′ to 3′.

Also shown are site selection results for each of the 48position-dependent GNN-recognizing zinc fingers. These show the numberof times a particular nucleotide was present, at a given position, in acollection of oligonucleotide sequences bound by the finger. Forexample, out of 15 oligonucleotides bound by a zinc finger protein withthe amino acid sequence QSGHLAR (SEQ ID NO:413) present at the finger 1(F1) position, 15 contained a G in the 5′-most position of the subsite,15 contained a G in the middle position of the subsite, while, at the3′-most position of the subsite, 10 contained an A, 3 contained a G and2 contained a T. Accordingly, this particular amino acid sequence isoptimal for binding a GGA triplet from the F1 position.

FIGS. 3A, 3B and 3C show site selection data indicating positionaldependence of GCA-, GAT- and GGT-binding zinc fingers. The first andfourth (where applicable) rows of each figure show portions of the aminoacid sequence of a designed zinc finger protein (F1 column, SEQ IDNOS:220, 1765, 1442, 835 & 1425; F2 column, SEQ ID NOS:220, 1765, 1442,889, 1425; F3 column, SEQ ID NOS:220, 159, 377, 889 & 1425). Amino acidresidues −1 through +6 of each α-helix are listed from left to right.The second and fifth (where applicable) rows show the target sequence,divided into three triplet subsites, one for each finger of the proteinshown in the first and fourth (where applicable) rows, respectively. Thethird and sixth (where applicable) rows show the distribution ofnucleotides in the oligonucleotides obtained by site selection with theproteins shown in the first and fourth (where applicable) rows,respectively. FIG. 3A shows data for fingers designed to bind GCA; FIG.3B shows data for fingers designed to bind GAT; FIG. 3C shows data forfingers designed to bind GGT.

The first row provides the amino acidsequences (F3, SEQ ID NO:1100; F2, SEQ ID NO:237; F1, SEQ ID NO:1450) ofresidues −1 through +6 of the recognition helices for each of the threezinc fingers of the EP2C protein. The second row shows the targetsequence (5′ to 3′); with the distribution of nucleotides in theoligonucleotides obtained by site selection indicated below the targetsequence.

FIG. 4B shows in vitro and in vivo assays for the binding specificity ofEP2C. The first three columns show in vitro measurements of bindingaffinity of EP2C to its intended target sequence and several relatedsequences. The first column gives the name of each sequence (2C0 is theintended target sequence, compare to FIG. 4A). The second column showsthe nucleotide sequence of various target sequences, with differencesfrom the intended target sequence (2C0) highlighted. The third columnshows the K_(d) (in nM) for binding of EP2C to each of the targetsequences. K_(d)s were determined by gel shift assays, using 2-folddilution series of EP2C. The right side of the figure (fourth column andbar graph) shows relative luciferase activities (normalized toβ-galactosidase levels) in stable cell lines in which expression of EP2Cis inducible. Cells were co-transfected with a vector containing aluciferase coding region under the transcriptional control of the targetsequence shown in the same row of the figure, and a control vectorencoding β-galactosidase. Luciferase and α-galactosidase levels weremeasured after induction of EP2C expression. Triplicate samples wereassayed and the standard deviations are shown in the bar graph. pGL3 isa luciferase-encoding vector lacking EP2C target sequences. 3B isanother negative control, in which luciferase expression is undertranscriptional control of sequences (3B) unrelated to the EP2C targetsequence.

Definitions

A zinc finger DNA binding protein is a protein or segment within alarger protein that binds DNA in a sequence-specific manner as a resultof stabilization of protein structure through coordination of a zincion. The term zinc finger DNA binding protein is often abbreviated aszinc finger protein or ZFP.

Zinc finger proteins can be engineered to recognize a selected targetsequence in a nucleic acid. Any method known in the art or disclosedherein can be used to construct an engineered zinc finger protein or anucleic acid encoding an engineered zinc finger protein. These include,but are not limited to, rational design, selection methods (e.g., phagedisplay) random mutagenesis, combinatorial libraries, computer design,affinity selection, use of databases matching zinc finger amino acidsequences with target subsite nucleotide sequences, cloning from cDNAand/or genomic libraries, and synthetic constructions. An engineeredzinc finger protein can comprise a new combination ofnaturally-occurring zinc finger sequences. Methods for engineering zincfinger proteins are disclosed in co-owned WO 00/41566 and WO 00/42219;as well as in WO 98/53057; WO 98/53058; WO 98/53059 and WO 98/53060; thedisclosures of which are hereby incorporated by reference in theirentireties. Methods for identifying preferred target sequences, and forengineering zinc finger proteins to bind to such preferred targetsequences, are disclosed in co-owned WO 00/42219.

A designed zinc finger protein is a protein not occurring in naturewhose design/composition results principally from rational criteria.Rational criteria for design include application of substitution rulesand computerized algorithms for processing information in a databasestoring information of existing ZFP designs and binding data.

A selected zinc finger protein is a protein not found in nature whoseproduction results primarily from an empirical process such as phagedisplay.

The term naturally-occurring is used to describe an object that can befound in nature as distinct from being artificially produced by man. Forexample, a polypeptide or polynucleotide sequence that is present in anorganism (including viruses) that can be isolated from a source innature and which has not been intentionally modified by man in thelaboratory is naturally-occurring. Generally, the termnaturally-occurring refers to an object as present in a non-pathological(undiseased) individual, such as would be typical for the species.

A nucleic acid is operably linked when it is placed into a functionalrelationship with another nucleic acid sequence. For instance, apromoter or enhancer is operably linked to a coding sequence if itincreases the transcription of the coding sequence. Operably linkedmeans that the DNA sequences being linked are typically contiguous and,where necessary to join two protein coding regions, contiguous and inreading frame. However, since enhancers generally function whenseparated from the promoter by up to several kilobases or more andintronic sequences may be of variable lengths, some polynucleotideelements may be operably linked but not contiguous.

A specific binding affinity between, for example, a ZFP and a specifictarget site means a binding affinity of at least 1×10⁶ M⁻¹.

The terms “modulating expression” “inhibiting expression” and“activating expression” of a gene refer to the ability of a zinc fingerprotein to activate or inhibit transcription of a gene. Activationincludes prevention of subsequent transcriptional inhibition (i.e.,prevention of repression of gene expression) and inhibition includesprevention of subsequent transcriptional activation (i.e., prevention ofgene activation). Modulation can be assayed by determining any parameterthat is indirectly or directly affected by the expression of the targetgene. Such parameters include, e.g., changes in RNA or protein levels,changes in protein activity, changes in product levels, changes indownstream gene expression, changes in reporter gene transcription(luciferase, CAT, beta-galactosidase, GFP (see, e.g., Mistili & Spector,Nature Biotechnology 15:961-964 (1997)); changes in signal transduction,phosphorylation and dephosphorylation, receptor-ligand interactions,second messenger concentrations (e.g., cGMP, cAMP, IP3, and Ca2+), cellgrowth, neovascularization, in vitro, in vivo, and ex vivo. Suchfunctional effects can be measured by any means known to those skilledin the art, e.g., measurement of RNA or protein levels, measurement ofRNA stability, identification of downstream or reporter gene expression,e.g., via chemiluminescence, fluorescence, colorimetric reactions,antibody binding, inducible markers, ligand binding assays; changes inintracellular second messengers such as cGMP and inositol triphosphate(IP3); changes in intracellular calcium levels; cytokine release, andthe like.

A “regulatory domain” refers to a protein or a protein subsequence thathas transcriptional modulation activity. Typically, a regulatory domainis covalently or non-covalently linked to a ZFP to modulatetranscription. Alternatively, a ZFP can act alone, without a regulatorydomain, or with multiple regulatory domains to modulate transcription.

A D-able subsite within a target site has the motif 5′NNGK3′ (SEQ IDNO:4084). A target site containing one or more such motifs is sometimesdescribed as a D-able target site. A zinc finger appropriately designedto bind to a D-able subsite is sometimes referred to as a D-able finger.Likewise a zinc finger protein containing at least one finger designedor selected to bind to a target site including at least one D-ablesubsite is sometimes referred to as a D-able zinc finger protein.

DETAILED DESCRIPTION

I. General

Tables 1-5 list a collection of normaturally occurring zinc fingerprotein sequences and their corresponding target sites. The first columnof each table is an internal reference number. The second column lists a9 or 10 base target site bound by a three-finger zinc finger protein,with the target sites listed in 5′ to 3′ orientation. The third columnprovides SEQ ID NOs for the target site sequences listed in column 2.The fourth, sixth and eighth columns list amino acid residues from thefirst, second and third fingers, respectively, of a zinc finger proteinwhich recognizes the target sequence listed in the second column. Foreach finger, seven amino acids, occupying positions −1 to +6 of thefinger, are listed. The numbering convention for zinc fingers is definedbelow. Columns 5, 7 and 9 provide SEQ ID NOs for the amino acidsequences listed in columns 4, 6 and 8, respectively. The final columnof each table lists the binding affinity (i.e., the K_(d) in nM) of thezinc finger protein for its target site. Binding affinities are measuredas described below.

Each finger binds to a triplet of bases within a corresponding targetsequence. The first finger binds to the first triplet starting from the3′ end of a target site, the second finger binds to the second triplet,and the third finger binds the third (i.e., the 5′-most) triplet of thetarget sequence. For example, the RSDSLTS finger (SEQ ID NO: 646) ofSBS# 201 (Table 2) binds to 5′TTG3′, the ERSTLTR finger (SEQ ID NO: 851)binds to 5′GCC3′ and the QRADLRR finger (SEQ ID NO:1056) binds to5′GCA3′.

Table 6 lists a collection of consensus sequences for zinc fingers andthe target sites bound by such sequences. Conventional one letter aminoacid codes are used to designate amino acids occupying consensuspositions. The symbol “X” designates a nonconsensus position that can inprinciple be occupied by any amino acid. In most zinc fingers of theC₂H₂ type, binding specificity is principally conferred by residues −1,+2, +3 and +6. Accordingly, consensus sequence determining bindingspecificity typically include at least these residues. Consensussequences are useful for designing zinc fingers to bind to a giventarget sequence. Residues occupying other positions can be selectedbased on sequences in Tables 1-5, or other known zinc finger sequences.Alternatively, these positions can be randomized with a plurality ofcandidate amino acids and screened against one or more target sequencesto refine binding specificity or improve binding specificity. Ingeneral, the same consensus sequence can be used for design of a zincfinger regardless of the relative position of that finger in amulti-finger zinc finger protein. For example, the sequence RXDNXXR (SEQID NO:4060) can be used to design a N-terminal, central or C-terminalfinger of three finger protein. However, some consensus sequences aremost suitable for designing a zinc finger to occupy a particularposition in a multi-finger protein. For example, the consensus sequenceRXDHXXQ (SEQ ID NO:4055) is most suitable for designing a C-terminalfinger of a three-finger protein.

II. Characteristics of Zinc Finger Proteins

Zinc finger proteins are formed from zinc finger components. Forexample, zinc finger proteins can have one to thirty-seven fingers,commonly having 2, 3, 4, 5 or 6 fingers. A zinc finger proteinrecognizes and binds to a target site (sometimes referred to as a targetsegment) that represents a relatively small subsequence within a targetgene. Each component finger of a zinc finger protein can bind to asubsite within the target site. The subsite includes a triplet of threecontiguous bases all on the same strand (sometimes referred to as thetarget strand). The subsite may or may not also include a fourth base onthe opposite strand that is the complement of the base immediately 3′ ofthe three contiguous bases on the target strand. In many zinc fingerproteins, a zinc finger binds to its triplet subsite substantiallyindependently of other fingers in the same zinc finger protein.Accordingly, the binding specificity of zinc finger protein containingmultiple fingers is usually approximately the aggregate of thespecificities of its component fingers. For example, if a zinc fingerprotein is formed from first, second and third fingers that individuallybind to triplets XXX, YYY, and ZZZ, the binding specificity of the zincfinger protein is 3′XXX YYY ZZZ5′.

The relative order of fingers in a zinc finger protein from N-terminalto C-terminal determines the relative order of triplets in the 3′ to 5′direction in the target. For example, if a zinc finger protein comprisesfrom N-terminal to C-terminal first, second and third fingers thatindividualy bind, respectively, to triplets 5′ GAC3′, 5′GTA3′ and5″GGC3′ then the zinc finger protein binds to the target segment3′CAGATGCGG5′. If the zinc finger protein comprises the fingers inanother order, for example, second finger, first finger, third finger,then the zinc finger protein binds to a target segment comprising adifferent permutation of triplets, in this example, 3′ATGCAGCGG5′ (seeBerg & Shi, Science 271, 1081-1086 (1996)). The assessment of bindingproperties of a zinc finger protein as the aggregate of its componentfingers may, in some cases, be influenced by context-dependentinteractions of multiple fingers binding in the same protein.

Two or more zinc finger proteins can be linked to have a targetspecificity that is the aggregate of that of the component zinc fingerproteins (see e.g., Kim & Pabo, PNAS 95, 2812-2817 (1998)). For example,a first zinc finger protein having first, second and third componentfingers that respectively bind to XXX, YYY and ZZZ can be linked to asecond zinc finger protein having first, second and third componentfingers with binding specificities, AAA, BBB and CCC. The bindingspecificity of the combined first and second proteins is thus3′XXXYYYZZZ______AAABBBCCC5′, where the underline indicates a shortintervening region (typically 0-5 bases of any type). In this situation,the target site can be viewed as comprising two target segmentsseparated by an intervening segment.

Linkage can be accomplished using any of the following peptide linkers.T G E K P: (SEQ. ID. No:2) (Liu et al., 1997, supra.); (G4S)n (SEQ. ID.No:3) (Kim et al., PNAS 93, 1156-1160 (1996.); GGRRGGGS; (SEQ. ID. No:4)LRQRDGERP; (SEQ. ID. No:5) LRQKDGGGSERP; (SEQ. ID. No:6) LRQKD (G3S)2ERP (SEQ. ID. No:7) Alternatively, flexible linkers can be rationallydesigned using computer programs capable of modeling both DNA-bindingsites and the peptides themselves or by phage display methods. In afurther variation, noncovalent linkage can be achieved by fusing twozinc finger proteins with domains promoting heterodimer formation of thetwo zinc finger proteins. For example, one zinc finger protein can befused with fos and the other with jun (see Barbas et al., WO 95/119431).

Linkage of two zinc finger proteins is advantageous for conferring aunique binding specificity within a mammalian genome. A typicalmammalian diploid genome consists of 3×10⁹ bp. Assuming that the fournucleotides A, C, G, and T are randomly distributed, a given 9 bpsequence is present ˜23,000 times. Thus a ZFP recognizing a 9 bp targetwith absolute specificity would have the potential to bind to ˜23,000sites within the genome. An 18 bp sequence is present once in 3.4×10¹⁰bp, or about once in a random DNA sequence whose complexity is ten timesthat of a mammalian genome.

A component finger of zinc finger protein typically contains about 30amino acids and has the following motif (N—C): (SEQ. ID. No:8) Cys-(X)₂₋₄-Cys-X.X.X.X.X.X.X.X.X.X.X.X-His- (X)₃₋₅-His                         −1 1 2 3 4 5 6 7

The two invariant histidine residues and two invariant cysteine residuesin a single beta turn are co-ordinated through zinc (see, e.g., Berg &Shi, Science 271, 1081-1085 (1996)). The above motif shows a numberingconvention that is standard in the field for the region of a zinc fingerconferring binding specificity. The amino acid on the left (N-terminalside) of the first invariant His residues is assigned the number +6, andother amino acids further to the left are assigned successivelydecreasing numbers. The alpha helix begins at residue 1 and extends tothe residue following the second conserved histidine. The entire helixis therefore of variable length, between 11 and 13 residues.

The process of designing or selecting a normaturally occurring orvariant ZFP typically starts with a natural ZFP as a source of frameworkresidues. The process of design or selection serves to definenonconserved positions (i.e., positions −1 to +6) so as to confer adesired binding specificity. One suitable ZFP is the DNA binding domainof the mouse transcription factor Zif268. The DNA binding domain of thisprotein has the amino acid sequence: (SEQ. ID. No:9)YACPVESCDRRFSRSDELTRHIRIHTGQKP (F1) (SEQ. ID. No:10)FQCRICMRNFSRSDHLTTHIRTHTGEKP (F2) (SEQ. ID. No:11)FACDICGRKFARSDERKRHTKIHLRQK (F3) (SEQ. ID. No:12) and binds to a target5′ GCG TGG GCG 3′.

Another suitable natural zinc finger protein as a source of frameworkresidues is Sp-1. The Sp-1 sequence used for construction of zinc fingerproteins corresponds to amino acids 531 to 624 in the Sp-1 transcriptionfactor. This sequence is 94 amino acids in length. The amino acidsequence of Sp-1 is as follows: (SEQ. ID. No:13)PGKKKQHICHIQGCGKVYGKTSHLRAHLRWHTGERPFMCTWSYCGKRFTRSDELQRHKRTHTGEKKFACPECPKRFMRSDHLSKHIKTHQNKKG (SEQ. ID. No:14) Sp-1 bindsto a target site 5′ GGG GCG GGG 3′.

An alternate form of Sp-1, an Sp-1 consensus sequence, has the followingamino acid sequence:

-   meklrngsgd-   PGKKKQHACPECGKSFSKSSHLRAHQRTHTGERP-   YKCPECGKSFSRSDELQRHQRTHTGEKP    YKCPECGKSFSRSDHLSKHQRTHQNKKG (SEQ. ID. NO: 15) (lower case letters    are a leader sequence from Shi & Berg, Chemistry and Biology 1,    83-89. (1995). The optimal binding sequence for the Sp-1 consensus    sequence is 5′GGGGCGGGG3′ (SEQ ID NO: 16). Other suitable ZFPs are    described below.

There are a number of substitution rules that assist rational design ofsome zinc finger proteins (see Desjarlais & Berg, PNAS 90, 2256-2260(1993); Choo & Klug, PNAS 91, 11163-11167 (1994); Desjarlais & Berg,PNAS 89, 7345-7349 (1992); Jamieson et al., supra; Choo et al., WO98/53057, WO 98/53058; WO 98/53059; WO 98/53060). Many of these rulesare supported by site-directed mutagenesis of the three-finger domain ofthe ubiquitous transcription factor, Sp-1 (Desjarlais and Berg, 1992;1993). One of these rules is that a 5′ G in a DNA triplet can be boundby a zinc finger incorporating arginine at position 6 of the recognitionhelix. Another substitution rule is that a G in the middle of a subsitecan be recognized by including a histidine residue at position 3 of azinc finger. A further substitution rule is that asparagine can beincorporated to recognize A in the middle of triplet, aspartic acid,glutamic acid, serine or threonine can be incorporated to recognize C inthe middle of triplet, and amino acids with small side chains such asalanine can be incorporated to recognize T in the middle of triplet. Afurther substitution rule is that the 3′ base of triplet subsite can berecognized by incorporating the following amino acids at position −1 ofthe recognition helix: arginine to recognize G, glutamine to recognizeA, glutamic acid (or aspartic acid) to recognize C, and threonine torecognize T. Although these substitution rules are useful in designingzinc finger proteins they do not take into account all possible targetsites. Furthermore, the assumption underlying the rules, namely that aparticular amino acid in a zinc finger is responsible for binding to aparticular base in a subsite is only approximate. Context-dependentinteractions between proximate amino acids in a finger or binding ofmultiple amino acids to a single base or vice versa can cause variationof the binding specificities predicted by the existing substitutionrules.

The technique of phage display provides a largely empirical means ofgenerating zinc finger proteins with a desired target specificity (seee.g., Rebar, U.S. Pat. No. 5,789,538; Choo et al., WO 96/06166; Barbaset al., WO 95/19431 and WO 98/543111; Jamieson et al., supra). Themethod can be used in conjunction with, or as an alternative to rationaldesign. The method involves the generation of diverse libraries ofmutagenized zinc finger proteins, followed by the isolation of proteinswith desired DNA-binding properties using affinity selection methods. Touse this method, the experimenter typically proceeds as follows. First,a gene for a zinc finger protein is mutagenized to introduce diversityinto regions important for binding specificity and/or affinity. In atypical application, this is accomplished via randomization of a singlefinger at positions −1, +2, +3, and +6, and sometimes accessorypositions such as +1, +5, +8 and +10. Next, the mutagenized gene iscloned into a phage or phagemid vector as a fusion with gene III of afilamentous phage, which encodes the coat protein pIII. The zinc fingergene is inserted between segments of gene III encoding the membraneexport signal peptide and the remainder of pilI, so that the zinc fingerprotein is expressed as an amino-terminal fusion with pIII or in themature, processed protein. When using phagemid vectors, the mutagenizedzinc finger gene may also be fused to a truncated version of gene IIIencoding, minimally, the C-terminal region required for assembly of pIIIinto the phage particle. The resultant vector library is transformedinto E. coli and used to produce filamentous phage which express variantzinc finger proteins on their surface as fusions with the coat proteinpIII. If a phagemid vector is used, then the this step requiressuperinfection with helper phage. The phage library is then incubatedwith target DNA site, and affinity selection methods are used to isolatephage which bind target with high affinity from bulk phage. Typically,the DNA target is immobilized on a solid support, which is then washedunder conditions sufficient to remove all but the tightest bindingphage. After washing, any phage remaining on the support are recoveredvia elution under conditions which disrupt zinc finger—DNA binding.Recovered phage are used to infect fresh E. coli., which is thenamplified and used to produce a new batch of phage particles. Selectionand amplification are then repeated as many times as is necessary toenrich the phage pool for tight binders such that these may beidentified using sequencing and/or screening methods. Although themethod is illustrated for pIII fusions, analogous principles can be usedto screen ZFP variants as pVIII fusions.

In certain embodiments, the sequence bound by a particular zinc fingerprotein is determined by conducting binding reactions (see, e.g.,conditions for determination of K_(d), infra) between the protein and apool of randomized double-stranded oligonucleotide sequences. Thebinding reaction is analyzed by an electrophoretic mobility shift assay(EMSA), in which protein-DNA complexes undergo retarded migration in agel and can be separated from unbound nucleic acid. Oligonucleotideswhich have bound the finger are purified from the gel and amplified, forexample, by a polymerase chain reaction. The selection (i.e. bindingreaction and EMSA analysis) is then repeated as many times as desired,with the selected oligonucleotide sequences. In this way, the bindingspecificity of a zinc finger protein having a particular amino acidsequence is determined.

Zinc finger proteins are often expressed with a heterologous domain asfusion proteins. Common domains for addition to the ZFP include, e.g.,transcription factor domains (activators, repressors, co-activators,co-repressors), silencers, oncogenes (e.g., myc, jun, fos, myb, max,mad, rel, ets, bcl, myb, mos family members etc.); DNA repair enzymesand their associated factors and modifiers; DNA rearrangement enzymesand their associated factors and modifiers; chromatin associatedproteins and their modifiers (e.g. kinases, acetylases anddeacetylases); and DNA modifying enzymes (e.g., methyltransferases,topoisomerases, helicases, ligases, kinases, phosphatases, polymerases,endonucleases) and their associated factors and modifiers. A preferreddomain for fusing with a ZFP when the ZFP is to be used for represssingexpression of a target gene is a KRAB repression domain from the humanKOX−1 protein (Thiesen et al., New Biologist 2, 363-374 (1990); Margolinet al., Proc. Natl. Acad. Sci. USA 91, 4509-4513 (1994); Pengue et al.,Nucl. Acids Res. 22:2908-2914 (1994); Witzgall et al., Proc. Natl. Acad.Sci. USA 91, 4514-4518 (1994). Preferred domains for achievingactivation include the HSV VP16 activation domain (see, e.g., Hagmann etal., J. Virol. 71, 5952-5962 (1997)) nuclear hormone receptors (see,e.g., Torchia et al., Curr. Opin. Cell. Biol. 10:373-383 (1998)); thep65 subunit of nuclear factor kappa B (Bitko & Barik, J. Virol.72:5610-5618 (1998) and Doyle & Hunt, Neuroreport 8:2937-2942 (1997));Liu et al., Cancer Gene Ther. 5:3-28 (1998)), or artificial chimericfunctional domains such as VP64 (Seifpal et al., EMBO J. 11, 4961-4968(1992)).

An important factor in the administration of polypeptide compounds, suchas the ZFPs, is ensuring that the polypeptide has the ability totraverse the plasma membrane of a cell, or the membrane of anintra-cellular compartment such as the nucleus. Cellular membranes arecomposed of lipid-protein bilayers that are freely permeable to small,nonionic lipophilic compounds and are inherently impermeable to polarcompounds, macromolecules, and therapeutic or diagnostic agents.However, proteins and other compounds such as liposomes have beendescribed, which have the ability to translocate polypeptides such asZFPs across a cell membrane.

For example, “membrane translocation polypeptides” have amphiphilic orhydrophobic amino acid subsequences that have the ability to act asmembrane-translocating carriers. In one embodiment, homeodomain proteinshave the ability to translocate across cell membranes. The shortestinternalizable peptide of a homeodomain protein, Antennapedia, was foundto be the third helix of the protein, from amino acid position 43 to 58(see, e.g., Prochiantz, Current Opinion in Neurobiology 6:629-634(1996)). Another subsequence, the h (hydrophobic) domain of signalpeptides, was found to have similar cell membrane translocationcharacteristics (see, e.g., Lin et al., J. Biol. Chem. 270:1 4255-14258(1995)).

Examples of peptide sequences which can be linked to a ZFP, forfacilitating uptake of ZFP into cells, include, but are not limited to:an 11 amino acid peptide of the tat protein of HIV; a 20 residue peptidesequence which corresponds to amino acids 84-103 of the p 16 protein(see Fahraeus et al., Current Biology 6:84 (1996)); the third helix ofthe 60-amino acid long homeodomain of Antennapedia (Derossi et al., J.Biol. Chem. 269:10444 (1994)); the h region of a signal peptide such asthe Kaposi fibroblast growth factor (K-FGF) h region (Lin et al.,supra); or the VP22 translocation domain from HSV (Elliot & O'Hare, Cell88:223-233 (1997)). Other suitable chemical moieties that provideenhanced cellular uptake may also be chemically linked to ZFPs.

Toxin molecules also have the ability to transport polypeptides acrosscell membranes. Often, such molecules are composed of at least two parts(called “binary toxins”): a translocation or binding domain orpolypeptide and a separate toxin domain or polypeptide. Typically, thetranslocation domain or polypeptide binds to a cellular receptor, andthen the toxin is transported into the cell. Several bacterial toxins,including Clostridium perfringens iota toxin, diphtheria toxin (DT),Pseudomonas exotoxin A (PE), pertussis toxin (PT), Bacillus anthracistoxin, and pertussis adenylate cyclase (CYA), have been used in attemptsto deliver peptides to the cell cytosol as internal or amino-terminalfusions (Arora et al., J. Biol. Chem., 268:3334-3341 (1993); Perelle etal., Infect. Immun., 61:5147-5156 (1993); Stenmark et al., J. Cell Biol.113:1025-1032 (1991); Donnelly et al., PNAS 90:3530-3534 (1993);Carbonetti et al., Abstr. Annu. Meet. Am. Soc. Microbiol. 95:295 (1995);Sebo et al., Infect. Immun. 63:3851-3857 (1995); Klimpel et al., PNASU.S.A. 89:10277-10281 (1992); and Novak et al., J. Biol. Chem.267:17186-17193 1992)).

Such subsequences can be used to translocate ZFPs across a cellmembrane. ZFPs can be conveniently fused to or derivatized with suchsequences. Typically, the translocation sequence is provided as part ofa fusion protein. Optionally, a linker can be used to link the ZFP andthe translocation sequence. Any suitable linker can be used, e.g., apeptide linker.

III. Position Dependence Of Subsite Recognition By Zinc Fingers

A number of the polypeptides disclosed herein have been characterizedusing the methods disclosed in U.S. Pat. No. 6,794,136; which maturedfrom a grandparent of the present application (the disclosure of whichis hereby incorporated by reference in its entirety); in particular withrespect to the effect of their position, within a multi-finger protein,on their sequence specificity. The results of these investigationsprovide a set of zinc finger sequences that are optimized forrecognition of certain triplet target subsites whose 5′-most nucleotideis a G (i.e., GNN triplet subsites). Thus, particular zinc fingersequences which recognize each of the GNN triplet subsites, from eachposition of a three-finger zinc finger protein, are provided. See FIG.2. It will be clear to those of skill in the art that the optimized,position-specific zinc finger sequences disclosed herein for recognitionof GNN target subsites are not limited to use in three-finger proteins.For example, they are also useful in six-finger proteins, which can bemade by linkage of two three-finger proteins.

A number of zinc finger amino acid sequences which are reported to bindto target subsites in which the 5′-most nucleotide residue is G (i.e.,GNN subsites) have recently been disclosed. Segal et al. (1999) Proc.Natl. Acad. Sci. USA 96:2758-2763; Drier et al. (2000) J. Mol. Biol.303:489-502; U.S. Pat. No. 6,140,081. These GNN-binding zinc fingerswere obtained by selection of finger 2 sequences from phage displaylibraries of three-finger proteins, in which certain amino acid residuesof finger 2 had been randomized. Due to the manner in which they wereselected, it is not clear whether these sequences would have the sametarget subsite specificity if they were present in the F1 and/or F3positions.

Use of the methods and compositions disclosed herein has now allowedidentification of specific zinc finger sequences that bind each of the16 GNN triplet subsites, and for the first time, provides zinc fingersequences that are optimized for recognition of these triplet subsitesin a position-dependent fashion. Moreover, in vivo studies of theseoptimized designs reveal that the functionality of a ZFP is correlatedwith its binding affinity to its target sequence. See Example 6, infra.

As a result of the discovery, disclosed herein, that sequencerecognition by zinc fingers is position-dependent, it is clear thatexisting design rules will not, in and of themselves, be applicable toevery situation in which it is necessary to construct asequence-specific ZFP. The results disclosed herein show that many zincfingers that are constructed based on design rules exhibit the sequencespecificity predicted by those design rules only at certain fingerpositions. The position-specific zinc fingers disclosed herein arelikely to function more efficiently in vivo and in cultured cells, withfewer nonspecific effects. Highly specific ZFPs, made usingposition-specific zinc fingers, will be useful tools in studying genefunction and will find broad applications in areas as diverse as humantherapeutics and plant engineering.

IV. Production of Zinc Finger Proteins ZFP polypeptides and nucleicacids encoding the same can be made using routine techniques in thefield of recombinant genetics. Basic texts disclosing the generalmethods include Sambrook et al., Molecular Cloning, A Laboratory Manual(2nd ed. 1989); Kriegler, Gene Transfer and Expression: A LaboratoryManual (1990); and Current Protocols in Molecular Biology (Ausubel etal., eds., 1994)). In addition, nucleic acids less than about 100 basescan be custom ordered from any of a variety of commercial sources, suchas The Midland Certified Reagent Company (mcrc@oligos.com), The GreatAmerican Gene Company (http://www.genco.com), ExpressGen Inc.(www.expressgen.com), Operon Technologies Inc. (Alameda, Calif.).Similarly, peptides can be custom ordered from any of a variety ofsources, such as PeptidoGenic (pkim@ccnet.com), HTI Bio-products, inc.(http://www.htibio.com), BMA Biomedicals Ltd (U.K.), Bio. Synthesis,Inc.

Oligonucleotides can be chemically synthesized according to the solidphase phosphoramidite triester method first described by Beaucage &Caruthers, Tetrahedron Letts. 22:1859-1862 (1981), using an automatedsynthesizer, as described in Van Devanter et al., Nucleic Acids Res.12:6159-6168 (1984). Purification of oligonucleotides is by eitherdenaturing polyacrylamide gel electrophoresis or by reverse phase HPLC.The sequence of the cloned genes and synthetic oligonucleotides can beverified after cloning using, e.g., the chain termination method forsequencing double-stranded templates of Wallace et al., Gene 16:21-26(1981).

Two alternative methods are typically used to create the codingsequences required to express newly designed DNA-binding peptides. Oneprotocol is a PCR-based assembly procedure that utilizes six overlappingoligonucleotides (FIG. 1). Three oligonucleotides (oligos 1, 3, and 5 inFIG. 1) correspond to “universal” sequences that encode portions of theDNA-binding domain between the recognition helices. Theseoligonucleotides typically remain constant for all zinc fingerconstructs. The other three “specific” oligonucleotides (oligos 2, 4,and 6 in FIG. 1) are designed to encode the recognition helices. Theseoligonucleotides contain substitutions primarily at positions −1, 2, 3and 6 on the recognition helices making them specific for each of thedifferent DNA-binding domains.

The PCR synthesis is carried out in two steps. First, a double strandedDNA template is created by combining the six oligonucleotides (threeuniversal, three specific) in a four cycle PCR reaction with a lowtemperature annealing step, thereby annealing the oligonucleotides toform a DNA “scaffold.” The gaps in the scaffold are filled in byhigh-fidelity thermostable polymerase, the combination of Taq and Pfupolymerases also suffices. In the second phase of construction, the zincfinger template is amplified by external primers designed to incorporaterestriction sites at either end for cloning into a shuttle vector ordirectly into an expression vector.

An alternative method of cloning the newly designed DNA-binding proteinsrelies on annealing complementary oligonucleotides encoding the specificregions of the desired ZFP. This particular application requires thatthe oligonucleotides be phosphorylated prior to the final ligation step.This is usually performed before setting up the annealing reactions. Inbrief, the “universal” oligonucleotides encoding the constant regions ofthe proteins (oligos 1, 2 and 3 of above) are annealed with theircomplementary oligonucleotides. Additionally, the “specific”oligonucleotides encoding the finger recognition helices are annealedwith their respective complementary oligonucleotides. Thesecomplementary oligos are designed to fill in the region which waspreviously filled in by polymerase in the above-mentioned protocol. Thecomplementary oligos to the common oligos 1 and finger 3 are engineeredto leave overhanging sequences specific for the restriction sites usedin cloning into the vector of choice in the following step. The secondassembly protocol differs from the initial protocol in the followingaspects: the “scaffold” encoding the newly designed ZFP is composedentirely of synthetic DNA thereby eliminating the polymerase fill-instep, additionally the fragment to be cloned into the vector does notrequire amplification. Lastly, the design of leaving sequence-specificoverhangs eliminates the need for restriction enzyme digests of theinserting fragment. Alternatively, changes to ZFP recognition helicescan be created using conventional site-directed mutagenesis methods.

Both assembly methods require that the resulting fragment encoding thenewly designed ZFP be ligated into a vector. Ultimately, theZFP-encoding sequence is cloned into an expression vector. Expressionvectors that are commonly utilized include, but are not limited to, amodified pMAL-c2 bacterial expression vector (New England BioLabs or aneukaryotic expression vector, pcDNA (Promega). The final constructs areverified by sequence analysis.

Any suitable method of protein purification known to those of skill inthe art can be used to purify ZFPs (see, Ausubel, supra, Sambrook,supra). In addition, any suitable host can be used for expression, e.g.,bacterial cells, insect cells, yeast cells, mammalian cells, and thelike.

Expression of a zinc finger protein fused to a maltose binding protein(MBP-ZFP) in bacterial strain JM109 allows for straightforwardpurification through an amylose column (NEB). High expression levels ofthe zinc finger chimeric protein can be obtained by induction with IPTGsince the MBP-ZFP fusion in the pMal-c2 expression plasmid is under thecontrol of the tac promoter (NEB). Bacteria containing the MBP-ZFPfusion plasmids are inoculated into 2xYT medium containing 10 μM ZnCl2,0.02% glucose, plus 50 μg/ml ampicillin and shaken at 37° C. Atmid-exponential growth IPTG is added to 0.3 mM and the cultures areallowed to shake. After 3 hours the bacteria are harvested bycentrifugation, disrupted by sonication or by passage through a frenchpressure cell or through the use of lysozyme, and insoluble material isremoved by centrifugation. The MBP-ZFP proteins are captured on anamylose-bound resin, washed extensively with buffer containing 20 mMTris-HCl (pH 7.5), 200 mM NaCl, 5 mM DTT and 50 μM ZnCl2, then elutedwith maltose in essentially the same buffer (purification is based on astandard protocol from NEB). Purified proteins are quantitated andstored for biochemical analysis.

The dissociation constants of the purified proteins, e.g., Kd, aretypically characterized via electrophoretic mobility shift assays (EMSA)(Buratowski & Chodosh, in Current Protocols in Molecular Biology pp.12.2.1-12.2.7 (Ausubel ed., 1996)). Affinity is measured by titratingpurified protein against a fixed amount of labeled double-strandedoligonucleotide target. The target typically comprises the naturalbinding site sequence flanked by the 3 bp found in the natural sequenceand additional, constant flanking sequences. The natural binding site istypically 9 bp for a three-finger protein and 2×9 bp+intervening basesfor a six finger ZFP. The annealed oligonucleotide targets possess a 1base 5′ overhang which allows for efficient labeling of the target withT4 phage polynucleotide kinase. For the assay the target is added at aconcentration of 1 nM or lower (the actual concentration is kept atleast 10-fold lower than the expected dissociation constant), purifiedZFPs are added at various concentrations, and the reaction is allowed toequilibrate for at least 45 min. In addition the reaction mixture alsocontains 10 mM Tris (pH 7.5), 100 mM KCl, 1 mM MgCl2, 0.1 mM ZnCl2, 5 mMDTT, 10% glycerol, 0.02% BSA. (NB: in earlier assays poly d(IC) was alsoadded at 10-100 μg/μl.)

The equilibrated reactions are loaded onto a 10% polyacrylamide gel,which has been pre-run for 45 min in Tris/glycine buffer, then bound andunbound labeled target is resolved by electrophoresis at 150V.(alternatively, 10-20% gradient Tris-HCl gels, containing a 4%polyacrylamide stacker, can be used) The dried gels are visualized byautoradiography or phosphorimaging and the apparent Kd is determined bycalculating the protein concentration that gives half-maximal binding.

The assays can also include determining active fractions in the proteinpreparations. Active fractions are determined by stoichiometric gelshifts where proteins are titrated against a high concentration oftarget DNA. Titrations are done at 100, 50, and 25% of target (usuallyat micromolar levels).

V. Applications of Engineered Zinc Finger Proteins

ZPFs that bind to a particular target gene, and the nucleic acidsencoding them, can be used for a variety of applications. Theseapplications include therapeutic methods in which a ZFP or a nucleicacid encoding it is administered to a subject and used to modulate theexpression of a target gene within the subject. See, for example,co-owned WO 00/41566. The modulation can be in the form of repression,for example, when the target gene resides in a pathological infectingmicrorganisms, or in an endogenous gene of the patient, such as anoncogene or viral receptor, that is contributing to a disease state.Alternatively, the modulation can be in the form of activation whenactivation of expression or increased expression of an endogenouscellular gene can ameliorate a diseased state. For such applications,ZFPs, or more typically, nucleic acids encoding them are formulated witha pharmaceutically acceptable carrier as a pharmaceutical composition.

Pharmaceutically acceptable carriers are determined in part by theparticular composition being administered, as well as by the particularmethod used to administer the composition. (see, e.g., Remington'sPharmaceutical Sciences, 17^(th) ed. 1985)). The ZFPs, alone or incombination with other suitable components, can be made into aerosolformulations (i.e., they can be “nebulized”) to be administered viainhalation. Aerosol formulations can be placed into pressurizedacceptable propellants, such as dichlorodifluoromethane, propane,nitrogen, and the like. Formulations suitable for parenteraladministration, such as, for example, by intravenous, intramuscular,intradermal, and subcutaneous routes, include aqueous and non-aqueous,isotonic sterile injection solutions, which can contain antioxidants,buffers, bacteriostats, and solutes that render the formulation isotonicwith the blood of the intended recipient, and aqueous and non-aqueoussterile suspensions that can include suspending agents, solubilizers,thickening agents, stabilizers, and preservatives. Compositions can beadministered, for example, by intravenous infusion, orally, topically,intraperitoneally, intravesically or intrathecally. The formulations ofcompounds can be presented in unit-dose or multi-dose sealed containers,such as ampules and vials. Injection solutions and suspensions can beprepared from sterile powders, granules, and tablets of the kindpreviously described.

The dose administered to a patient should be sufficient to effect abeneficial therapeutic response in the patient over time. The dose isdetermined by the efficacy and K_(d) of the particular ZFP employed, thetarget cell, and the condition of the patient, as well as the bodyweight or surface area of the patient to be treated. The size of thedose also is determined by the existence, nature, and extent of anyadverse side-effects that accompany the administration of a particularcompound or vector in a particular patient

In other applications, ZFPs are used in diagnostic methods for sequencespecific detection of target nucleic acid in a sample. For example, ZFPscan be used to detect variant alleles associated with a disease orphenotype in patient samples. As an example, ZFPs can be used to detectthe presence of particular mRNA species or cDNA in a complex mixtures ofmRNAs or cDNAs. As a further example, ZFPs can be used to quantify copynumber of a gene in a sample. For example, detection of loss of one copyof a p53 gene in a clinical sample is an indicator of susceptibility tocancer. In a further example, ZFPs are used to detect the presence ofpathological microorganisms in clinical samples. This is achieved byusing one or more ZFPs specific to genes within the microorganism to bedetected. A suitable format for performing diagnostic assays employsZFPs linked to a domain that allows immobilization of the ZFP on anELISA plate. The immobilized ZFP is contacted with a sample suspected ofcontaining a target nucleic acid under conditions in which binding canoccur. Typically, nucleic acids in the sample are labeled (e.g., in thecourse of PCR amplification). Alternatively, unlabelled probes can bedetected using a second labelled probe. After washing, bound-labellednucleic acids are detected.

ZFPs also can be used for assays to determine the phenotype and functionof gene expression. Current methodologies for determination of genefunction rely primarily upon either overexpression or removing (knockingout completely) the gene of interest from its natural biological settingand observing the effects. The phenotypic effects observed indicate therole of the gene in the biological system.

One advantage of ZFP-mediated regulation of a gene relative toconventional knockout analysis is that expression of the ZFP can beplaced under small molecule control. By controlling expression levels ofthe ZFPs, one can in turn control the expression levels of a generegulated by the ZFP to determine what degree of repression orstimulation of expression is required to achieve a given phenotypic orbiochemical effect. This approach has particular value for drugdevelopment. By putting the ZFP under small molecule control, problemsof embryonic lethality and developmental compensation can be avoided byswitching on the ZFP repressor at a later stage in mouse development andobserving the effects in the adult animal. Transgenic mice having targetgenes regulated by a ZFP can be produced by integration of the nucleicacid encoding the ZFP at any site in trans to the target gene.Accordingly, homologous recombination is not required for integration ofthe nucleic acid. Further, because the ZFP is trans-dominant, only onechromosomal copy is needed and therefore functional knock-out animalscan be produced without backcrossing.

EXAMPLES Example 1 Initial Design of Zinc Finger Proteins andDetermination of Binding Affinity

Initial ZFP designs were based on existing design rules, correspondenceregimes and ZFP directories, including those disclosed herein (seeTables 1-5) and also in WO 98/53058; WO 98/530059; WO 98/53060 andco-owned U.S. patent application Ser. No. 09/444,241. See also WO00/42219. Amino acid sequences were conceptually designed using aminoacids 532-624 of the human transcription factor Sp1 as a backbone.Polynucleotides encoding designed ZFPs were assembled using a PolymeraseChain Reaction (PCR)-based procedure that utilizes six overlappingoligonucleotides. PCR products were directly cloned cloning into the Tacpromoter vector, pMal-c2 (New England Biolabs, Beverly, Mass.) using theKpnI and BamHI restriction sites. The encoded maltose bindingprotein-ZFP fusion polypeptides were purified according to themanufacturer's procedures (New England Biolabs, Beverly, Mass.). Bindingaffinity was measured by gel mobility-shift analysis. All of theseprocedures are described in detail in co-owned WO 00/41566 and WO00/42219, as well as in Zhang et al. (2000) J. Biol. Chem.275:33,850-33,860 and Liu et al. (2001) J. Biol. Chem. 276:11, 323-11,334; the disclosures of which are hereby incorporated by reference intheir entireties.

Example 2 Optimization of Binding Specificity by Site Selection

Designed ZFPs were tested for binding specificity using site selectionmethods disclosed in parent application U.S. Ser. No. 09/716,637 filedNov. 20, 2000, now U.S. Pat. No. 6,794,136. Briefly, designed proteinswere incubated with a population of labeled, double-strandedoligonucleotides comprising a library of all possible 9- or10-nucleotide target sequences. Five nanomoles of labeledoligonucleotides were incubated with protein, at a protein concentration4-fold above its K_(d) for its target sequence. The mixture wassubjected to gel electrophoresis, and bound oligonucleotides wereidentified by mobility shift, and extracted from the gel. The purifiedbound oligonucleotides were amplified, and the amplification productswere used for a subsequent round of selection. At each round ofselection, the protein concentration was decreased by 2 fold. After 3-5rounds of selection, amplification products were cloned into the TOPO TAcloning vector (Invitrogen, Carlsbad, Calif.), and the nucleotidesequences of approximately 20 clones were determined. The identities ofthe target sites bound by a designed protein were determined from thesequences and expressed as a compilation of subsite binding sequences.

Example 3 Comparison of Site Selection Results with Binding Affinity

To test the correlation between site selection results and the affinityof binding of a ZFP to various related targets, site selectionexperiments were conducted on 2 three-finger ZFPs, denoted ZFP1 andZFP2, and the site selection results were compared with K_(d)measurements obtained from quantitative gel-mobility shift assays usingthe same ZFPs and target sites. Each ZFP was constructed, based ondesign rules, to bind to a particular nine-nucleotide target sequence(comprising 3 three-nucleotide subsites), as shown in FIG. 1. Siteselection results and affinity measurements are also shown in FIG. 1.The site selection results showed that fingers 1 and 3 of both the ZFP1and ZFP2 proteins preferentially selected their intended targetsequences. However, the second finger of each ZFP preferentiallyselected subsites other than those to which they were designed to bind(e.g., F2 of ZFP1 was designed to bind TCG, but preferentially selectedGTG; F2 of ZFP2 was designed to bind GGT, but preferentially selectedGGA).

To confirm the site selection results, binding affinities of ZFP1 andZFP2 were measured (see Example 1, supra), both to their original targetsequences and to new target sequences reflecting the site selectionresults. For example, the Mt-1 sequence contains two base changes(compared to the original target sequence for ZFP1) which result in achange in the sequence of the finger 2 subsite to GTG, reflecting thepreferred finger 2 subsite sequence obtained by site selection. Inagreement with the site selection results, binding of ZFP1 to the Mt-1sequence is approximately 4-fold stronger than its binding to theoriginal target sequence (K_(d) of 12.5 nM compared to a K_(d) of 50 nM,see FIG. 1).

For ZFP2, the specificity of finger 2 for the 3′ base of its targetsubsite was tested, since, although this finger was designed to bindGGT, site selection indicated that it bound preferentially to GGA.Moreover, the site selection results predicted that finger 2 of ZFP2would bind with approximately equal affinity to GGT and GGC.Accordingly, target sequences containing GGA (Mt-3) and GGC (Mt-4) atthe finger 2 subsite were constructed, and binding affinities of ZFP2 tothese target sequences, and to its original target sequence (containingGGT at the finger 2 subsite), were compared. In complete agreement withthe site selection results, ZFP2 exhibited the strongest bindingaffinity for the target sequence containing GGA at the finger 2 subsite(K_(d) of 0.5 nM, FIG. 1), and its affinity for target sequencescontaining either GGT or GGC at the finger 2 subsite was approximatelyequal (K_(d) of 1 nM for both targets, FIG. 1). Accordingly, the siteselection method, in addition to being useful for iterative optimizationof binding specificity, can also be used as a useful indicator ofbinding affinity.

Example 4 Use of Site Selection to Identify Position-Dependent,GNN-Binding Zinc Fingers

A large number of engineered ZFPs have been evaluated, by siteselection, to identify zinc fingers that bind to GNN target subsites. Inthe course of these studies, it became apparent that the bindingspecificity of a particular zinc finger sequence is, in some instances,dependent upon the position of the zinc finger in the protein, and henceupon the location of the target subsite within the target sequence. Forexample, if one wishes to design a three-finger zinc finger protein tobind to a target sequence containing the triplet subsite GAT, it isnecessary to know whether this subsite is the first, second or thirdsubsite in the target sequence (i.e., whether the GAT subsite will bebound by the first, second or third finger of the protein). Accordingly,over 110 three-finger zinc finger proteins, containing potentialGNN-recognizing zinc fingers in various locations, have been evaluatedby site selection experiments. Generally, several zinc finger sequenceswere designed to recognize each GNN triplet, and each design was testedin each of the F1, F2 and F3 positions through 4 to 6 rounds ofselection.

The results of these analyses, shown in FIG. 2, provide optimalposition-dependent zinc finger sequences (the sequences shown representamino acid residues −1 through +6 of the recognition helix portion ofthe finger) for recognition of the 16 GNN target subsites, as well assite selection results for these GNN-specific zinc fingers. Optimalamino acid sequences for recognition of each GNN subsite from each ofthree positions (finger 1, finger 2 or finger 3) are thereby provided.

GNG Binding Finger Designs

The amino acid sequence RSDXLXR (SEQ ID NO:4085) (position −1 to +6 ofthe recognition helix) was found to be optimal for binding to the fourGNG triplets, with Asn⁺³ specifying A as the middle nucleotide; His⁺³specifying G as the middle nucleotide; Ala⁺³ specifying T as the middlenucleotide; and Asp⁺³ specifying cytosine as the middle nucleotide. Atthe +5 position, Ala, Thr, Ser, and Gln, were tested, and all showedsimilar specificity profiles by site selection. Interestingly, and incontrast to a previous report (Swimoff et al. (1995) Mol. Cell. Biol.15:2275-2287), site selection results indicated that threenaturally-occurring GCG-binding fingers from zif268 and Sp1, having theamino acid sequences RSDELTR (SEQ ID NO:123), RSDELQR (SEQ ID NO:302),and RSDERKR (SEQ ID NO:1100), were not GCG-specific. Rather, each ofthese fingers selected almost equal numbers of GCG and GTG sequences.Analysis of binding affinity by gel-shift experiments confirmed thatfinger 3 of zif268, having the sequence RSDERKR (SEQ ID NO:1000), bindsGCG and GTG with approximately equal affinity.

Position Dependence of GCA-, GAT-, GGT-, GAA- and GCC-Binding Fingers

Based on existing design rules, the amino acid sequence QSGDLTR (SEQ IDNO:220) (−1 through +6) was tested for its ability to bind the GCAtriplet from three positions (F1, F2, and F3) within a three-finger ZFP.FIG. 3A shows that the QSGDLTR (SEQ ID NO:220) sequence boundpreferentially to the GCA triplet subsite from the F2 and F3 positions,but not from F1. In fact, the presence of QSGDLTR (SEQ ID NO:220) at theF1 position of three different three-finger ZFPs resulted predominantlyin selection of GCT. Accordingly, an attempt was made to redesign thissequence to obtain specificity for GCA from the F1 position. Since thesequence Q⁻¹G⁺²S⁺³R⁺⁶ (SEQ ID NO:4065) had previously been selected froma randomized F1 library using GCA as target (Rebar et al. (1994) Science263:671-673), a D (asp) to S (ser) change was made at the +3 residue ofthis finger. The resulting sequence, QSGSLTR (SEQ ID NO:342), was testedfor its binding specificity by site selection and found topreferentially bind GCA, from the F1 position, in three different ZFPs(see FIG. 2).

The QSGSLTR (SEQ ID NO:342) zinc finger, optimized for recognition ofthe GCA subsite from the F1 position, was tested for its selectivitywhen located at the F2 position. Accordingly, two ZFPs, one containingQSGSLTR (SEQ ID NO:342) at finger 2 and one containing QSGDLTR (SEQ IDNO:220) at finger 2 (both having identical F1 sequences and identical F3sequences) were tested by site selection. The results indicated that,when used at the F2 position, QSGSLTR (SEQ ID NO:342) boundpreferentially to GTA, rather than GCA. Thus, for optimal binding of aGCA triplet subsite from the F1 position, the amino acid sequenceQSGSLTR (SEQ ID NO:342) is required; while, for optimal binding of thesame subsite sequence from F2 or F3, QSGDLTR (SEQ ID NO:220) should beused. Accordingly, different zinc finger amino acid sequences may beneeded to specify a particular triplet subsite sequence, depending uponthe location of the subsite within the target sequence and, hence, uponthe position of the finger in the protein.

Positional effects were also observed for zinc fingers recognizing GATand GGT subsites. The zinc finger amino acid sequence QSSNLAR (SEQ IDNO:1765) (−1 through +6) is expected to bind to GAT, based on designrules. However, this sequence selected GAT only from the F1 position,and not from the F2 and F3 positions, from which the sequence GAA waspreferentially bound (FIG. 3B). Similarly, the amino acid sequenceQSSHLTR (SEQ ID NO:835) which, based on design rules, should bind GGT,selected GGT at the F1 position, but not at the F2 and F3 positions,from which it preferentially bound GGA (FIG. 3C). Conversely, the aminoacid sequence TSGHLVR (SEQ ID NO:1425) has previously been disclosed torecognize the triplet GGT, based on its selection from a randomizedlibrary of zif268 finger 2. U.S. Pat. No. 6,140,081. However, TSGHLVR(SEQ ID NO:1425) was not specific for the GGT subsite when located atthe F1 position (FIG. 3C). These results indicate that the bindingspecificity of many fingers is position dependent, and particularlypoint out that the sequence specificity of a zinc finger selected from aF2 library may be positionally limited.

The results shown in FIG. 2 indicate that recognition of at least GAAand GCC triplets by zinc fingers is also position dependent.

These positional dependences stand in contrast to earlier publishedwork, which suggested that zinc fingers behaved as independent moduleswith respect to the sequence specificity of their binding to DNA.Desjarlais et al. (1993) Proc. Natl. Acad. Sci. USA 90:2256-2260.

Example 5 Characterization of EP2C

The engineered zinc finger protein EP2C binds to a target sequence,GCGGTGGCT with a dissociation constant (K_(d)) of 2 nM. Site selectionresults indicated that fingers 1 and 2 are highly specific for theirtarget subsites, while finger 3 selects GCG (its intended targetsubsite) and GTG at approximately equal frequencies (FIG. 4A). Toconfirm these observations, the binding affinities of EP2C to itscognate target sequence, and to variant target sequences, was measuredby standard gel-shift analyses (see Example 1, supra). As standards forcomparison, the binding affinities of Sp1 and zif268 to their respectivetargets were also measured under the same conditions, and weredetermined to be 40 nM for SP1 (target sequence GGGGCGGGG) and 2 nM forzif268 (target sequence GCGTGGGCG). Measurements of binding affinitiesconfirmed that F3 of EP2C bound GTG and GCG equally well (K_(d)s of 2nM), but bound GAG with a two-fold lower affinity (FIG. 4B). Finger 2was very specific for the GTG triplet, binding 15-fold less tightly to aGGG triplet (compare 2C0 and 2C3 in FIG. 4B). Finger 1 was also veryspecific for the GCT triplet, it bound with 4-fold lower affinity to aGAT triplet (2C4) and with 2-fold lower affinity to a GCG triplet (2C5).This example shows, once again, the high degree of correlation betweensite selection results and binding affinities.

Example 6 Evaluation of Engineered ZFPs by In Vivo Functional Assays

To determine whether a correlation exists between the binding affinityof a engineered ZFP to its target sequence and its functionality invivo, cell-based reporter gene assays were used to analyze thefunctional properties of the engineered ZFP EP2C (see Example 5, supra).For these assays, a plasmid encoding the EP2C ZFP, fused to a VP16transcriptional activation domain, was used to construct a stable cellline (T-Rex-293™, Invitrogen, Carlsbad, Calif.) in which expression ofEP2C-VP16 is inducible, as described in Zhang et al., supra. To generatereporter constructs, three tandem copies of the EP2C target site, or itsvariants (see FIG. 4B, column 2), were inserted between the Mlu I andBglII sites of the pGL3 luciferase-encoding vector (Promega, Madison,Wis.), upstream of the SV40 promoter. Structures of all reporterconstructs were confirmed by DNA sequencing.

Luciferase reporter assays were performed by co-transfection ofluciferase reporter construct (200 ng) and pCMV-βgal (100 ng, used as aninternal control) into the EP2C cells seeded in 6-well plates.Expression of the EP2C-VP16 transcriptional activator was induced withdoxycycline (0.05 ug/ml) 24 h after transfection of reporter constructs.Cell lysates were harvested 40 hours post-transfection, luciferase andβ-galactosidase activities were measured by the Dual-Light ReporterAssay System (Tropix, Bedford, Mass.), and luciferase activities werenormalized to the co-transfected α-galactosidase activities. Theresults, shown on the right side of FIG. 4B, showed that the normalizedluciferase activity for each reporter construct was well correlated withthe in vitro binding affinity of EP2C to the target sequence present inthe construct. For example, the target sequences to which EP2C boundwith greatest affinity (2C0 and 2C2, K_(d) of 2 nM for each) bothstimulated the highest levels of luciferase activity, when used to driveluciferase expression in the reporter construct (FIG. 4B). Targetsequences to which EP2C bound with 2-fold lower affinity, 2C1 and 2C5(K_(d) of 4 nM for each), stimulated roughly half the luciferaseactivity of the 2C0 and 2C2 targets. The 2C3 and 2C4 sequences, forwhich EP2C showed the lowest in vitro binding affinities, also yieldedthe lowest levels of in vivo activity when used to drive luciferaseexpression. Target 3B, a sequence to which EP2C does not bind, yieldedbackground levels of luciferase activity, similar to those obtained witha luciferase-encoding vector lacking EP2C target sequences (pGL3). Thusthere exist good correlations between binding affinity (as determined byK_(d) measurement), binding specificity (as determined by siteselection) and in vivo functionality for engineered zinc fingerproteins.
